Conduct soil and/or foliar nutrient analysis to confirm that the problem is nutritional. Follow recommended practices for fertility using a balanced fertilizer. High pH soils often induce iron deficiency by holding iron in an insoluble form. Powdered sulfur applications may be used on limited areas to lower pH. A number of chelated iron compounds are available for spray application

1. Heera 303

6. Iron Deficiency
Symptoms:
Iron-deficient plants are yellow and
stunted, with the symptoms
expressed on the young leaves first.
Affected leaves have interveinal
chlorosis, with the leaf lamina at first
appearing to be a "healthy" yellow.
Control:
Conduct soil and/or foliar nutrient
analysis to confirm that the problem
is nutritional. Follow recommended
practices for fertility using a balanced
fertilizer. High pH soils often induce
iron deficiency by holding iron in an
insoluble form. Powdered sulfur
applications may be used on limited
areas to lower pH. A number of
chelated iron compounds are
available for spray application.

7. Manganese Deficiency
Symptoms:
Manganese-deficient plants
stunted, leaves are yellow and
mottled, with the symptoms
expressed on the young leaves
first.
Control:
Conduct soil and/or foliar
nutrient analysis to confirm
that the problem is nutritional.
Follow recommended practices
for fertility using a balanced
fertilizer. High pH soils often
induce manganese deficiency
by holding manganese in an
insoluble form.

8. Zn Deficiency
Zinc deficiency on citrus tree. Note "blotchy"
Interveinal chlorosis on young leaves. Often
also causes a rosette-like whirl of stunted
leaves in a symptom called "little leaf".
Zinc on corn (maize). Note the broad band of
whitish or chlorotic tissue on either side of the
mid-rib, especially on mature leaves.

9. Copper deficiency in plants
Copper deficiency in barley. Note whitish leaf tips
poorly unfolded. Most common on acid sandy soils

10. Molybdenum deficiency in plants
Symptoms:
Molybdenum deficiency is characterized
by a whitish-tan interveinal chlorosis
accompanied by marginal leaf burn in
severe cases. Older leaves are affected
first. Plants are usually severely stunted.
Control:
Conduct soil and/or foliar nutrient
analysis to confirm that the problem is
nutritional. Follow recommended
practices for fertility using a balanced
fertilizer and treat for alkalinity or
acidity as needed.
